In this article, we discuss the types of Java certification, explain the benefits of pursuing them and outline tips on how to get these qualifications.
Types of Java certification
If you're a programming professional, there are different types of Java certification that you can pursue to prove your proficiency in this language. Java is an object-oriented programming language that runs across a wide range of platforms. You can use it to write applications for different platforms. Once developers write a Java-based application, they can run the same code on all platforms that have Java Runtime Environment (JRE) without recompiling the code.
Having a Java certification can show you have the expertise to use this language to perform programming tasks competently. While many companies provide Java courses, the Oracle Corporation offers certifications that many IT professionals recognise as creditable. Here's a list of some of the Oracle Java certifications you may consider:
1. Oracle Certified Associate (OCA), Java SE 8 Programmer Certification
This is a beginner certification that measures a candidate's understanding of the basics of Java programming. It involves passing the Java SE 8 Programmer I examination. This tests candidates on their knowledge of different topics, such as their abilities to develop Java code, apply Java operators and create loop constructs. Gaining this qualification is the first step to showing that you have the skills to become a professional Java developer. Those who earn this certification can:
define the structure of a Java class
differentiate between object reference variables and primitive variables
use Java operators
2. Oracle Certified Professional Java Programmer (OCPJP), Java SE 8 Programmer II
